             Summary: STS Renew returns incorrect lifetime
                 Key: CXF-5278
                 URL: https://issues.apache.org/jira/browse/CXF-5278
             Project: CXF
          Issue Type: Improvement
          Components: STS
    Affects Versions: 2.7.6
            Reporter: Ethan Wallwork


SAMLTokenRenewer#renewToken sets the lifetime attribute of the 
TokenRenwerResponse to the difference between the NotBefore and NotOnOrAfter 
attributes of the SAML assertion conditions.  Later the 
TokenRenewOperation#createREsponse method creates a Lifetime using the current 
timestamp as the Created value and the current timestamp plus the previously 
calculated difference as the Expires.

In cases where the NotBefore of the SAML assertion conditions is not the 
current time this results in an incorrect lifetime in the response from the 
renew operation.  For example, if the NotBefore is a few minutes in the past to 
work around systems with clock differences then the lifetime in the response 
will claim the token expires a few minutes before it actually does.  

This seems to cause issues with caching of tokens on the client side 
(STSClient) as the token will be cached for a period shorter than it should be.
